我非柠檬为何心酸你非薄荷为何心凉
[wŏ fēi níng méng wéi hé xīn suān nĭ fēi bó hé wéi hé xīn liáng]
'If I'm Not a Lemon, Why Do I Feel Sour? If You're Not Peppermint, Why Do You Feel Cold?' The metaphor uses the sourness of lemons and the coolness of peppermint to describe feelings of bitterness or distance in a relationship.
